COLLARETTE-KNITTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 442,167, dated December9, 1890. Application filed November 25, 1889. $eria1 No. 331,441 (Nomodel.)

To aZZ whom, it may concern.-

3e it known that I, JOHN BRADLEY, of Chelmsford, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Oollarette- Knitting Machines, of which thefollowingis a specification.

My invention, in general, has relation to means for producingfancy-stitch work on spring-beard-needle knitting machines, and inparticular the invention has reference to collarette knitting machines,so called, which are designed to produce trimmings for knit underwear.

It is the object of the invention to produce improved means for throwingfigured presser-wheels into and out of operation in connection with theneedles, which means shall be simple in construction, economic ofmanufacture, and certain and efficient in operation, and which shall atthe same time be so organized as to effect the knitting of a variety ofpatterns.

The invention eomprehends the employment of a plurality of figuredpressers eapable of being moved into and out of operation in connectionwith the needles, so that the effect of plain pressing may beaccomplished at predetermined intervals, as well, also, as a variety oftuck or figured pressing, the movement of the pressers being secured bya mechanism peculiar, though simple, in construction and organization,all as is hereinafter fully and particularly set forth.

Reference is to be had to the annexed drawings and letters of referencemarked thereon, forming apart of this specification, the same lettersdesignating the same parts or features, as the case may be, whereverthey occur.

0f the drawings, Figure 1 is a perspective view of the invention, shownin connection with a spring-beard-needle knitting head or cylinder, theordinary appliances for operatin g in connection with the needles toproduce a knit fabric being, for the sake of clearness, omitted. Fig. 2is a sectional side elevation tending to show the construction of thepresser-support-s, their relation one to another, and also a part of themeans whereby the pressers may be moved. Fig. 3 is a plan view of thepressers, their supports, and operating means. Figs. 4 and 5 areseetional details hereinafter more particularly described.

In the drawings, a designates the needle head or cylinder, and l)spring-beard needles vertically arranged in the head, as usual. In theproduction of a fabric on a machine of this kind a yarn-guide,stitch-wheel, presserwheel,and landing and knocking-over wheels areemployed in away so well known to knitting artisans as not to needdescription herein, and to avoid complication and confusion I haveomitted all of the said devices from the drawings excepting the presserc, and instead of employing a plain-faced wheel, as is usually done, Imake use of a plurality of figured pressers, which, when actingconjointly, produce the same result as a plain presser, but which singlyare constructed so as to mispress the needles in different order. In thepresent instance I employ two such figured pressers d e, the formerbeing supported by and adapted to be rotated upon a study, secured tothe inner end of a lever g, and the latter being in like mannersupported on a stud h on the inner end of a lever 11. Both levers g and"i are fulerumed upon a stud j, attached to a star-130x70, adjustabletoward and from the needles, as is common with such devices inknitting-machines.

Z Z are bell-crank levers fulerumed at n on a bracket 0, connected withthe bed of the machine. The upper end of the lever Zis conneeted bymeans of a link m with the lever g, and the lever Z is connected bymeans of a link it with the lever 1 The links are pivotally connectedwith their respective levers g i, the pivot o of the link 11. extendingthrough a slot formed in the lever g, as is most clearly shown in Fig.4. Clips 7, secured to the lever g and extending over the pivotpins ofthe links, serve to keep the latter in place on the said pins.

The ends of the horizontal portions of the bell-crank lcversl Z areprovided with vertical'studs a 1', which are arranged to rest and rideupon the uppersurface of a pattern-disk s, as also upon and over thepattern-blocks 2, adapted to be secured to the disk 8 in the holes 11,formed therein.

The periphery of.

, block 25 passes under a stud ror r the bellcrank lever with which suchstud is connected will be operated so as to move the presserthe disk 3is provided with ratchet-teeth, which are engaged by a spring-pressedpawl 12, pivoted on the outer end of a lever 21;, fulcrumed on the bedof the machine, the inner end of said lever 10 being provided with abowl or roller 5r, arranged to be acted upon by a cam 3 on the head orcylinder a as the latter is rotated. A spring .2 (shown by dotted linesin Fig. 1) serves to actuate the lever 10 in a direction contrary tothat in which it is moved by cam y, the latter operation serving to movethe pattern-disk s a distance corresponding to the length of one of itsratchetteeth.

In operation, when plain knitting is to be performed, the pressers d 6will act conjointly andas a plain presser; but when it is desired toproduce tuck or fancy-stich Work one of the presscrs will be moved outof the way, so that but one can operate upon the needles, and this onewill press certain of the needles and mispress others, and then bothpress'ers may be again brought into action, as before,

or they may be made to change places, so that the one previously inoperation will bethrown out of action, and the one formerly out ofaction will be brought into operation and press and mispress the needlesin a different order. VVh-e-n the vertical studs 1' r are upon the faceof the patterndisk, the levers g 2' will be moved to a position whichwill bring both pressers into operation; but when a patterncarryinglever-,- w-ith'which it is connected through the medium of a linkrodi,in such manner as to throw its associated presserout of operation. Byproperly arranging thepattern-blocks on the pattern-disk the presse-rscan be thrown out of and brought into oper ation at any predeterminedtime or in any predetermined order.

Itis obvious that by varying the color of the yarns employed inaccordance with the changes made in the position of the pressers theeffect of the fancy stitching may be heightened.

Changes may be made in the form and arrangement of parts comprising myimprovements without departing from the nature or spirit of theinvention.

Having thus explained the nature of my invention and described a way ofconstructing and using the same, I declare that what I claim is-- 1. Thecombination, with the needle-cylinder and needles, of a plurality ofpressers, levers pivot-ed at one end and each supporting a presser atthe other, a rotary patterndisk, a plurality of levers adapted to beacted upon by the said pattern-disk, and means connecting the latterlevers with the presser-car rying levers, as set forth.

2. The combination, with the needle-cylinder and needles, of a leverpivoted at one end and supporting a presser-wheel at the other, a rotarypattern-disk, a bell-crank lever, and

a link connecting one end of the said bellcrank lever with the saidpresser-support-ing lever, the other end of the said bell-crank leverbeing arranged to be acted upon by the said rotary pattern-disk, as setforth.

In testimony whereof have signed my name to this specification, in thepresence of two subscribing witnesses, this 12th day of November, A. D.1889.

JOHN BRADLEY.
